PRODUCT DESCRIPTION: This Upgrade Spring for the Nerf Rival Vision improves the performance of the blaster bringing it up to the next level. The internals are similar to that of a Kronos making the install fairly easy. I suggest releasing the compression on the internal magazine before opening the blaster, do this by just opening the bottom of the magazine.
